Detailed description of the invention
For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.Preferred embodiment of the present invention is given in accompanying drawing.But the present invention can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present invention more comprehensively thorough.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.
As depicted in figs. 1 and 2, present embodiment discloses a kind of case drawbar endurance test machine fixture, it comprises load measuring gauge 10 (i.e. force measurement sensor), 20, two, the load measuring gauge seat of honour being connected with load measuring gauge 10 upper end lays respectively at the pull bar clamp system 30 of load measuring gauge 10 both sides, the holder 60 connecting load measuring gauge 10 and the button pressed downwards mechanism 50 be connected with the lower end of load measuring gauge 10.
Pull bar clamp system 30 comprise be connected with the load measuring gauge seat of honour 20 piston rod 31, with the cylinder body 32 that piston rod 31 is slidably connected and the hook 35 be connected with cylinder body 32; Cylinder body 32 is run through at the two ends of piston rod 31.During work, cylinder body 32 slides on piston rod 31 with hook 35, so that ribbon 352 is to the connection of hook 35 and case drawbar and tighten the ribbon 352 connecting hook 35 and case drawbar.
The hanger bulk 351 that hook 35 comprises ribbon 352 and is connected with cylinder body 32; Ribbon 352 is positioned at hanger bulk 351 one end away from the load measuring gauge seat of honour 20; Ribbon 352 comprises first end and the second end, and first end is fixedly connected with hanger bulk 351, and the second end is connected with hanger bulk 351 is adjustable.When wanting coupling hook 35 and case drawbar, as long as first the second end is taken off from hanger bulk 351, then by the cavity that the second end surrounds through case drawbar, finally the second end is fixed on drag hook body.By the second end of ribbon 352 is connected with hanger bulk 351 is adjustable, is convenient to hook 35 and is connected with the case drawbar of different model.
Piston rod 31 is arranged with spring 33, spring 33 is between cylinder body 32 and the load measuring gauge seat of honour 20.Arrange spring 33 by being located on piston rod 31, cylinder body 32 can not be contacted with the load measuring gauge seat of honour 20, avoiding collides between cylinder body 32 and the load measuring gauge seat of honour 20 damages.
Pull bar clamp system 30 also comprises spring shim 34, and spring shim 34 is sheathed on piston rod 31, and is positioned at the side of cylinder body 32 near spring 33.Spring shim 34 can prevent spring 33 to wear and tear cylinder body 32.
The both sides of ribbon 352 width are respectively arranged with baffle plate 354.By arranging baffle plate 354 respectively in the both sides of ribbon 352 width, case drawbar can not be contacted with hanger bulk 351, avoid the wearing and tearing of case drawbar to hanger bulk 351.
Baffle plate 354 adopts elastomeric material to make.By adopting elastomeric material to make on baffle plate 354; baffle plate 354 and case drawbar is made also to be soft contacts; avoid baffle plate 354 and namely avoid the wearing and tearing of case drawbar to hanger bulk 351, turn avoid its wearing and tearing to case drawbar, case drawbar can be protected better.
Side away from load measuring gauge 10 is provided with guide plate 353 to hanger bulk 351; On guide plate 353, corresponding piston rod 31 is provided with plate pilot hole; Piston rod 31 is through plate pilot hole.By arranging guide plate 353 and arrange the plate pilot hole making piston rod 31 pass on guide plate 353, hook 35 can be moved up and down stably.
Button pressed downwards mechanism 50 comprises the lower air cylinder 51 be connected with load measuring gauge 10 and the depression bar 52 be connected with the output shaft of lower air cylinder 51; Depression bar 52 is positioned at the below of lower air cylinder 51; Depression bar 52 is provided with pressure head 53 away from one end of lower air cylinder 51.After pull bar clamp system 30 connects case drawbar, when case drawbar endurance test machine fixture of the present invention will drive case drawbar to move upward, first will press the press button on case drawbar, this action is completed by button pressed downwards mechanism 50.When button pressed downwards mechanism 50 works, lower air cylinder 51 drives depression bar 52 to press down press button on case drawbar with dynamic head 53, till case drawbar can be stretched.
In the present embodiment, the upside at the load measuring gauge seat of honour 20 is provided with the pneumatic operated valve 70 be connected with lower air cylinder 51 and two cylinder bodies 32.
The outside of load measuring gauge 10 is coated with load measuring gauge 10 guard shield.Load measuring gauge 10 guard shield can protect load measuring gauge 10 by the injury of extraneous factor, can measure stress suffered by pull bar accurately to make load measuring gauge 10.
Case drawbar endurance test machine fixture operation principle of the present invention is as follows:
During work, with ribbon 352, hook 35 and case drawbar are tied up; After tying up, start cylinder body 32, cylinder body 32 moves up with hook 35, tightens with the ribbon 352 being used in coupling hook 35 and case drawbar; After ribbon 352 is tightened, lower air cylinder 51 drives depression bar 52 to press down with the press button on dynamic head 53 pairs of case drawbars, can be stretched to make case drawbar.
The present invention is by being provided with the hook 35 of ribbon 352, case drawbar endurance test machine fixture is connected by ribbon 352 with case drawbar, thus make that hook 35 and case drawbar are soft to be contacted, again by the mode of cylinder stretching ribbon 352, case drawbar is fixed rapidly, and can not case drawbar be damaged.Adopt the mode of ribbon binding case drawbar and case drawbar endurance test machine fixture in addition, this fixture can be fixed the case drawbar of difformity and specification, improve the versatility of case drawbar endurance test machine fixture of the present invention.
In addition, in order to ensure that hook 35 more stably moves up and down, in other embodiments, as shown in Figure 3, pull bar clamp system 30 also comprises the guide post 36 be connected with the top of cylinder body 32, the corresponding guide post 36 in the load measuring gauge seat of honour 20 is provided with seat of honour pilot hole, and guide post 36 passes seat of honour pilot hole away from one end of cylinder body 32.
The above embodiment only have expressed one embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
